With the implementation of Making Tax Digital (MTD), the UK’s tax system is going through its biggest change in a generation. HM Revenue & Customs (HMRC) is in charge of this massive government initiative, which is transforming the way individuals and businesses record, report, and pay their taxes from a paper-based system to a fully digital one.
While most businesses are now accustomed to MTD for VAT, 2025 is a crucial year for preparation, especially for independent contractors and landlords, as the required start date for MTD for Income Tax Self Assessment (ITSA) is quickly approaching.
In order to make sure you are compliant and prepared for the future of taxes, this thorough guide breaks down the essential requirements, deadlines, and preparation steps you must take in 2025.
Making Tax Digital is HMRC’s initiative to update the tax system. The goal is to make taxes easier to manage, help taxpayers avoid mistakes, and improve accuracy.
The core principle of MTD is simple:
• Digital Record Keeping: You must maintain records of your income and expenses digitally using MTD-compatible software.
• Digital Submissions: You must use this software to submit information directly to HMRC via a secure Application Programming Interface (API).
• Quarterly Updates: Instead of one annual tax return, MTD requires you to send updates to HMRC periodically throughout the tax year.
MTD for VAT is already required, and MTD for ITSA (Income Tax Self Assessment) will be the next significant rollout as the initiative is implemented in stages.
2025 is a year to take immediate action if you are not already in compliance with MTD for VAT. For others, it’s an important time to plan and make the switch to MTD for ITSA.
Status in 2025: Mandatory for All VAT Registered Businesses
MTD is now the accepted standard for VAT. All VAT-registered businesses, regardless of size, have been required to comply with them since April of 2022. Companies that are registered for VAT but violate the regulations run the risk of being fined.
Status in 2025: Preparatory Year for Mandatory Compliance
This is the most significant upcoming change. For millions of independent contractors and landlords, MTD for ITSA will take the place of the conventional Self Assessment tax return, radically altering the way taxes are reported. Although April 2026 is the earliest required start date, you should start preparing your systems and finances in 2025.
Depending on your qualifying income (total gross income from self-employment and/or property), the transition will be made gradually:
|
Mandatory Start Date
|
Qualifying Income Threshold
|
Affected Taxpayers
|
|---|---|---|
|
April 2026
|
Over £50,000 (Based on 2024/2025 tax year income)
|
Self-employed individuals and landlords.
|
|
April 2027
|
Over £30,000 (Based on 2025/2026 tax year income)
|
Self-employed individuals and landlords.
|
|
Future Phase
|
Below £30,000
|
HMRC is reviewing the position for those below this threshold.

Key ITSA Requirements:
• Digital Record Keeping: Income and expenses must be logged digitally throughout the year.
• Quarterly Updates: You will need to send four summary updates of your income and expenses to HMRC every tax year.
• End of Period Statement (EOPS): An annual declaration must be submitted for each business or property income source.
• Final Declaration: This is the final step, combining all income sources (including employment and pensions) to calculate your final tax liability. This will replace the current Self Assessment tax return.
Status in 2025: No Mandatory Timeline Yet, but Preparation is Advised
MTD for Corporation Tax for Limited Companies is still in the consultation stage, whereas MTD for VAT and ITSA have defined timelines. There is no mandatory start date in 2025. However, businesses will probably need to keep digital records and file returns using software that is compatible with the eventual rollout. To ensure a seamless transition when the time comes, limited companies are advised to keep their accounting procedures up to date and digital (Source: HMRC Guidance).
Let us help you streamline your tax compliance
The shift to digital record-keeping and the new submission schedule are the largest obstacles for the majority of businesses. Here is a clear action plan for 2025.
You must first determine whether and when you are required to comply.
• MTD for VAT: If you have a VAT registration, you need to comply right away. Make sure your system satisfies the requirement for digital links by reviewing it.
• For MTD for ITSA (Self-Employed/Landlords): Determine your income threshold for the 2024/2025 tax year.
○ If it is above £50,000, you are in the first wave and must be ready for April 2026.
○ If it is between £30,000 and £50,000, you are in the second wave, starting April 2027, but preparation should begin in 2025.
To precisely determine your start date, speak with an accountant or tax expert if your income is near the threshold or if you have several sources of income.
MTD needs specialised software that can use an API to directly communicate with HMRC’s systems. Manual entry systems or conventional spreadsheets are insufficient on their own.
• HMRC-Recognised Software: For both MTD for VAT and MTD for ITSA, choose a reliable cloud-based accounting programme that is listed on HMRC’s list of recognised software. Popular examples include Xero, QuickBooks, Sage, and FreeAgent.
• The Power of Cloud Accounting: Cloud-based software offers significant advantages, including:
○ Automatic bank feeds, reducing manual entry.
○ Real-time view of your financial position.
○ Automatic quarterly updates for MTD for ITSA.
• Bridging Software: If you rely heavily on complex spreadsheets, bridging software is an option. It acts as a digital link between your spreadsheet and HMRC’s API, allowing you to submit data correctly. However, migrating to a fully integrated accounting package is the long-term, most efficient solution.
For many, switching from paper files to digital records is the biggest adjustment. You have to make sure that all pertinent documents are kept digitally.
• Invoices and Receipts: Set up a system to collect and store digital copies of all of your invoices, receipts, and other pertinent documents. This system is typically included in your MTD-compatible software.
• Transaction Logging: Every transaction that affects your business’s income or expenditure must be recorded in your MTD software.
• Training: Ensure that the new software and the need for reliable, real-time digital record-keeping are thoroughly explained to you, your employees, or your contracted bookkeeper. Avoiding a stressful year-end rush requires the discipline of frequent digital updates.
Any significant change can be intimidating, but MTD is intended to modernise and streamline the tax system, providing both initial difficulties and substantial long-term advantages.
• Enhanced Accuracy: Automated computations and digital record-keeping significantly lower the possibility of human error that comes with manual data entry.
• Real-Time Financial Clarity: You and HMRC can plan and budget for tax payments more effectively thanks to the quarterly updates that provide a clearer, more current picture of your company’s financial situation.
• Simplified Year-End: Compiling a year’s worth of data at the last minute is much more difficult and time-consuming than the final End of Period Statement and Declaration because four quarterly updates have already been filed.
• Reduced Penalties: Fewer errors lead to fewer compliance issues and a reduced risk of penalties from HMRC. The new penalty system is point-based for late submissions, encouraging timely compliance.
• Streamlined Business Processes: By switching to integrated software, general bookkeeping, invoicing, and expense management are frequently streamlined, freeing up time for essential business operations.
• Initial Setup Costs: New software and possibly expert assistance are expenses. For a more economical move, look through HMRC’s list of free and inexpensive software options.
• Learning Curve: It takes time to adopt new technology. Invest in appropriate training or expert assistance and begin the transition well in advance of your required date in 2025.
• Quarterly Reporting Discipline: A new discipline is needed for the transition from annual to quarterly reporting. Every month or every quarter, set aside time to make sure your digital records are current.
• Data Security: Security is crucial when storing sensitive data digitally. Always use software that has been approved by HMRC and has strong security and data backup procedures.
HMRC is aware that not everyone is a good fit for MTD. There are some exceptions, but they are usually restricted and require an application:
• Digital Exclusion: If it is not reasonable or practical for you to use digital tools due to factors like age, disability, remote location with poor internet access, or religious beliefs that conflict with digital communications.
• Specific Business Types: Certain entities, such as trusts, estates, or non-resident companies, are currently exempt from the MTD for ITSA requirements.
You must review the most recent government guidelines and submit a formal application to HMRC if you think you are eligible for an exemption.
Moving away from immediate fines for minor tardiness, the new MTD penalty system is intended to be more equitable and consistent.
• Late Submissions (Quarterly Updates/Returns): This is based on a points system. After reaching a penalty points threshold, a financial penalty is issued. Points expire after a period of good compliance.
• Late Payments: Penalties are charged based on the length of time the payment is overdue, along with interest on the outstanding amount.
Although the main objective is to promote compliance through an open system, there will be financial penalties if you disregard MTD requirements after your required start date.
A permanent change towards a more effective and error-free tax system in the UK is represented by Making Tax Digital. The crucial year for preparation is 2025, even though the required MTD deadlines for ITSA are in 2026 and 2027.
Waiting until the last minute will increase the likelihood of mistakes and fines, cause needless stress, and result in bad software selections. By assessing your obligations, selecting compatible software, and implementing disciplined digital record-keeping now, you can transform the challenge of MTD into an opportunity for better business efficiency and financial control.
